The role of Bacteria in Agriculture:
The conversion of atmospheric nitrogen into forms of nitrogenous compounds usable by plants is. bacteria living in the root nodules of legume plants fix nitrogen from the atmosphere. Microorganisms in the soil convert atmospheric nitrogen into ammonium compounds, thereby enabling the plants and animals. Nitrogen is an essential constituent of nucleic acids, chlorophyll and vitamins. Rhizobium, Azobacter and Clostridium are species of bacteria which are capable of converting atmospheric nitrogen into forms usable by plants. Plants cannot use nitrogen in elemental form; hence the role of the nitrogen-fixing bacteria becomes very important
Nitrifying bacteria convert nitrogenous waste from dead plants and animals present in the soil into nitrates by the process called as nitrification. In this process, certain ammonifying bacteria like Bacillus and Clostridium first convert nitrogenous waste into ammonia. This ammonia is then converted into ammonium compounds by the same ammonifying bacteria. The ammonium compounds are then converted into nitrites by nitrifying bacteria such as Nitrosomonas, Nitrococcus and then into nitrates by nitrifying bacteria such as Nitrobacter.
Denitrifying bacteria like Pseudomonas putida and Bacillus subtilis are also present in the soil. These bacteria break down nitrates in the soil and release free nitrogen gas, which then enters the atmosphere.
Saprophytic bacteria obtain food from organic remains such as animal excreta, fallen leaves, meat etc. They decompose these substances by the action of digestive enzymes aerobically or anaerobically (known as fermentation). Thus they help in sanitation of nature, so also known as scavengers. E.g.Pseudomonas.
Bacteria, while converting animal dung and other organic wastes to manure, help in the production of fuel that is a must in gobar gas plant.
Bacteria help in disposal of sewage by decomposing it and thus, help in environmental sanitation.
